[0020] In order to further understand the invention content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0021] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 4 shown, a detection device for an electrical automation PLC provided by an embodiment of the present invention includes a main body 1, a protective shell 2, a connecting structure 3, a fixing block 4 and a fixing component 5. A control panel 101 is arranged on the front surface of the main body 1, and a protective shell 2 is sleeved on the outer surface of the control panel 101. Connecting blocks 201 are fixedly connected to both the left and right sides of the back surface of the protective shell 2. Connecting grooves 202 are formed on the back surfaces of the two connecting blocks 201, and limiting grooves 203 are formed on both the upper and lower sides of the inner walls of the two connecting grooves 202. Connecting structures 3 are fixedly connected to both the left and right sides of the main body 1. The connecting structure 3 includes a fixing block 4 and a fixing component 5, and the fixing component 5 is arranged inside the fixing block 4.

[0023] Referring to Figure 3 and Figure 4 , the two fixing blocks 4 are respectively fixedly connected to both the left and right sides of the main body 1. Sliding grooves 6 are formed on the sides of the two fixing blocks 4 away from each other, and openings 7 are formed on the front surfaces of the two fixing blocks 4. The two connecting blocks 201 are inserted into the inner walls of the fixing blocks 4 through the openings 7, and fixing arms 8 are fixedly connected to the sides of the inner walls of the two fixing blocks 4 close to each other.

[0024] Adopting the above scheme: by setting the fixing block 4, the fixing block 4 can cooperate with the fixing component 5 to work, and the connecting block 201 is fixed and limited through the connecting groove 202, so as to fixedly install the protective shell 2 on the surface of the main body 1 and wrap and protect the control panel 101.

[0025] Referring to Figure 3 and Figure 4, the fixing component 5 includes a sliding rod 9. The sliding rod 9 is arranged on the side of the fixing block 4 away from the main body 1. One end of the sliding rod 9 close to the main body 1 extends and penetrates through the inner wall of the fixing block 4. The outer surface of the sliding rod 9 is slidably connected to the inner wall of the sliding groove 6. A sliding block 10 is fixedly connected to one end of the sliding rod 9 extending into the fixing block 4 close to the main body 1.

[0026] With the above scheme: by setting the sliding rod 9, when the sliding rod 9 is toggled, the sliding rod 9 can slide on the inner wall of the sliding groove 6, and thereby drive the sliding block 10 to move.

[0027] Reference Figure 4 , the sliding block 10 is fixedly connected to one end of the sliding rod 9 extending into the fixing block 4. At both upper and lower ends on the side of the sliding block 10 away from the main body 1, limiting rods 11 are fixedly connected. On the side of the two limiting rods 11 away from each other, rotating arms 12 are arranged.

[0028] With the above scheme: by setting the sliding block 10, when the sliding block 10 moves, it can synchronously drive the two limiting rods 11 to move, so that the two limiting rods 11 respectively drive the two rotating arms 12 to rotate.

[0029] Reference Figure 4 , in the middle of the two rotating arms 12, they are rotatably connected to the inner wall of the fixing block 4 through a rotating shaft. The sides of the two rotating arms 12 close to each other are respectively in contact with the surfaces of the two limiting rods 11. On the surface of each of the two rotating arms 12 close to one end of the protective shell 2, a moving rod 13 is provided. The outer surfaces of the two moving rods 13 are sleeved with moving arms 14.

[0030] With the above scheme: by setting the rotating arms 12, when the two limiting rods 11 move, they respectively squeeze the two rotating arms 12 to make them rotate relatively. When the two rotating arms 12 rotate, they synchronously drive the two moving rods 13 to move, so as to respectively drive the two moving arms 14 to move.

[0031] Reference Figure 4 , the two moving arms 14 are both arranged on the side of the rotating arm 12 close to the main body 1. The sides of the two moving arms 14 close to the main body 1 are slidably connected to the surface of the fixed arm 8. In the middle of the two moving arms 14, moving grooves 15 are provided. The inner walls of the two moving grooves 15 are respectively in contact with the surfaces of the two moving rods 13. A return spring 16 is fixedly connected to the side of the two moving arms 14 close to each other. The sides of the front ends of the two moving arms 14 away from each other are respectively in contact with the upper and lower sides of the inner wall of the connecting groove 202. Limiting blocks 17 are respectively arranged on the side of the two moving arms 14 close to each other.

[0032] Adopting the above solution: By setting the moving arm 14, when the two moving rods 13 move, they drive the two moving arms 14 to slide away on the surface of the fixed arm 8 by squeezing the moving slots 15, and stretch the return spring 16. When the two moving arms 14 slide, they drive the two limit blocks 17 to move away respectively.

[0033] Reference Figure 4 , on the sides of the two limit blocks 17 facing away from each other, they are respectively fixedly connected to the sides of the two moving arms 14 facing each other, and the two limit blocks 17 are respectively inserted into the inner walls of the two limit slots 203.

[0034] Adopting the above solution: By setting the limit blocks 17, when the two limit blocks 17 are driven to move away, they can respectively disengage from the limit slots 203, thereby releasing the fixed limit on the connecting block 201, and the protective shell 2 can be removed to use the main body 1 for detection work.

[0035] The working principle of the present utility model:

[0036] During use, the sliding rod 9 is toggled backward. The sliding rod 9 slides in the sliding slot 6 and drives the sliding block 10 to move, causing the sliding block 10 to drive the two limit rods 11 to move synchronously. The two limit rods 11 move and respectively squeeze the surfaces of the two rotating arms 12, causing the two rotating arms 12 to rotate relative to each other. The two rotating arms 12 rotate and synchronously drive the two moving rods 13 to move. The two moving rods 13 move and drive the two moving arms 14 to slide away on the surface of the fixed arm 8 by squeezing the moving slots 15, and stretch the return spring 16. The two moving arms 14 slide away and simultaneously drive the two limit blocks 17 to move away, and the two limit blocks 17 respectively disengage from the limit slots 203 to release the fixed limit on the connecting block 201. Subsequently, the sliding rod 9 on the other side is repeatedly pulled to release the fixed limit on the other connecting block 201. Then, the protective shell 2 can be removed from the surface of the control panel 101, and the two connecting blocks 201 are respectively pulled out from the opening 7. Then, the control panel 101 is used in cooperation with the main body 1 for detection work. After completion, the main body 1 is closed and the protective shell 2 is sleeved on the outer surface of the control panel 101. Then, the two sliding rods 9 are respectively pulled to drive the two groups of moving arms 14 to slide away. Subsequently, the protective shell 2 is moved backward to drive the two connecting blocks 201 to be respectively inserted into the inner walls of the two fixed blocks 4 through the opening 7. Then, the two sliding rods 9 are released to enable the return spring 16 to reset and push the two groups of moving arms 14 to slide away, driving the two groups of limit blocks 17 to move away and be respectively inserted into the limit slots 203, thereby fixing and limiting the two connecting blocks 201, and completing the fixed installation of the protective shell 2 on the surface of the control panel 101 for wrapping and protection.

[0037] In summary, the detection device for the electrical automation PLC solves the problem that during the use of the temperature patrol instrument, components such as buttons and indicator lights on the control panel are vulnerable to physical damages such as external impacts and scratches without protection, which will not only affect the appearance of the instrument but may also lead to the failure of the control component functions through the coordinated work of the main body 1, the protective shell 2, the connection structure 3, the fixing block 4 and the fixing component 5.
